The main issue addressed in this article is the examination of Imam Khomeini's psychological operations during various phases of the Iran-Iraq War. Data were collected through content analysis of Imam Khomeini's messages concerning the war. The research hypothesis posited that Imam Khomeini's psychological operations in each of the four phases of the war (pre-war, from the onset of the war until the liberation of Khorramshahr, from the liberation of Khorramshahr to the acceptance of the ceasefire, and thereafter) were based on the social realities of society and the battlefield. The findings showed a significant relationship between the themes of Imam Khomeini's messages in each of these phases and the psychological management of society and the battlefield. In the first phase, the focus was on raising political awareness and influencing perceptions and motivation. In the second phase, emotional, sentimental, and motivational themes were dominant. In the third phase, logical persuasion of one's own side and psychological operations against the enemy were prevalent. In the fourth phase, calming society, as necessitated by the social context, was the central focus of psychological management in the messages. The results demonstrated that the significant relationship between Imam Khomeini's messages and the needs and social realities of the war was the most important factor contributing to the extensive impact of his psychological operations on society and the battlefield.
